I was mid-sentence explaining wave dynamics to a group of German tourists when the sky exploded. A relámpago lightning bolt struck the palm tree behind us, frying the WiFi router and sending two surf instructors diving into the sand. As the Germans screamed and my buddy Carlos laughed while wringing seawater from his socks, I realized: every weather app and travel blog had lied to these people. They’d promised “0% chance of rain” in November.
Here’s what you actually need to know about El Salvador’s weather, distilled from:
- 7 years running surf camps from El Tunco to Las Flores
- Arguments with 23 hotel managers about “rain guarantees”
- An old fisherman named Don Chava who predicts storms by watching iguana behavior
Chapter 1: The Dry Season Scam
December: The “Sunny” Month That Isn’t
What They Tell You:
“Perfect beach weather! Ideal for holiday travel!”
The Reality:
- December 5-20: The calmer winds die, trapping a visible brown haze of car exhaust over San Salvador (AQI hits 150+). Your “ocean view” becomes a smog panorama.
- Christmas Week: All wealthy Salvadorans flee to Miami, leaving beaches empty but prices jacked up 300%. The only people swimming are confused Canadians who didn’t get the memo.
Pro Tip: The caramel popcorn vendors at Plaza Gerardo Barrios only appear when humidity drops below 65%. Their sudden presence is a better weather indicator than any app.
True Story (2022): A French couple demanded a refund from their luxury resort because their “sunny December vacation” had three straight days of llovizna drizzle. The manager laughed while smoking a cigar under the eaves, then offered them free atol de elote instead.
January: The Cold You Weren’t Expecting
Blogger Lie: “Mild and dry mountain weather!”
Local Truth:
- Nights in Cerro Verde drop to 12°C (54°F) – locals bundle up in puffer jackets like it’s the Arctic
- Hotel pools in Santa Ana become unusable unless you enjoy swimming in what feels like liquid ice
Survival Move: Buy vanilla candles from roadside stands. They’re meant for religious altars but work wonders as hand warmers during volcano hikes.
